Imagine a world in which your laptop or mobile device accesses the internet, not via radio waves – or WiFi – as it does today but by using light instead: LiFi. Well, that world may not be as far away as you might think. In fact, the technology is already here; and it’s thanks in large part to the engineering ingenuity of Harald Haas, Distinguished Professor of Mobile Communications and Director of the Li-Fi Research and Development Centre at the University of Strathclyde.

2023/08/21

Anne-Marie Imafidon passed her computing A-Level at the age of 11 and by 16, was accepted to the University of Oxford to study Maths and Computer Science. She's used to the 'child prodigy' label that's followed her throughout her career, but that doesn't mean she's had an easy ride. It was a combination of personal experience and the discovery that the number of women working in the STEM sectors - Science, Technology, Engineering and Mathematics - was in free-fall that inspired Anne-Marie to found

Our genes can tell us so much about us, from why we look the way we look, think the way we think, even what kind of diseases we might be likely to suffer from. But our genes aren't the whole story. There are other, complex and intriguing systems within every cell in our bodies which control which of our tens-of-thousands of genes are switched on, or off, in different parts of the body, and under different circumstances. Welcome to the fascinating world of 'epigenetics', which our guest, the

2023/08/07

From landslides and wildfires to floods and tornadoes, Bruce Malamud has spent his career travelling the world and studying natural hazards. Today, he is Wilson Chair of Hazard and Risk and Executive Director of the Institute of Hazard, Risk and Resilience at Durham University - but as he tells Jim Al-Khalili, a lifelong passion for discovery has taken Bruce from volunteering with the Peace Corps in West Africa and a Fulbright Fellowship in Argentina, to fieldwork in India; not only studying

The Life Scientific: Andre Geim

2023/07/31

The world around us is three-dimensional. Yet, there are materials that can be regarded as two-dimensional. They are only one layer of atoms thick and have remarkable properties that are different from their three-dimensional counterparts. Sir Andre Geim created the first-ever man-made 2D material, by isolating graphene, and is one of the pioneers in this line of research. Even beyond his Nobel Prize-winning work on graphene, he has explored new ideas in many different areas of physics throughout

In Search of Stardust

Discovery ·

2023/07/24

Norwegian jazz musician Jon Larsen was having breakfast one clear spring morning when he noticed a tiny black speck land on his clean, white table. With no wind, birds or planes in sight, he wondered if it fell from space. Dust from space isn’t as fanciful as it sounds. Billions of microscopic meteorites, dating back to the birth of our solar system, fall onto Earth every year. But they are so tiny, hidden among the copious dust of everyday life, that scientists believe they are impossible to

We've been building computers to think like us for years, but our ability to replicate human senses has been impossible. Until now. Evolutionary biologist and broadcaster Professor Ben Garrod, is off to meet some of the sensory innovators and technological pioneers who are developing human like-sensing technology. From skin patches that can read our sugar levels, to brain implants that could use our thoughts to control computers. This is the technology that could blur the boundary between body,

In The Evidence on the BBC World Service, Claudia Hammond will be exploring the concept of solastalgia; broadly defined as the pain or emotional suffering brought about by environmental change close to your home or cherished place. Made in collaboration with Wellcome Collection, Claudia Hammond and an expert panel examine this relatively new concept, one that might be increasingly heard about as the effects of climate change are felt. Claudia will be hearing stories of solastalgia from

James Gallagher get's behind the hype to find out if sperm counts are really falling? There are plenty of headlines telling us they are, but also scientists who disagree - he unpicks the evidence with two of them. James also gets his own sperm sample analysed and meets a couple who found the reason behind their low count was one of the leading causes of male infertility.

Psychedelics

2023/06/05

James Gallagher reports on a psychedelic renaissance; a new wave of research testing hallucinogenic drugs like magic mushrooms to treat mental health conditions. There’s genuine excitement and some early encouraging evidence. A manufacturer tells James that in five years’ time, it’s possible that psychedelics could be part of the medicine cabinet – but with the hype, there’s risk too and there’s much still to learn about who these drugs could help and how.

There is a bizarre number in maths referred to simply as ‘i’. It appears to break the rules of arithmetic - but turns out to be utterly essential for applications across engineering and physics. We are talking about the square root of -1, which makes no sense. Professor Fry waxes lyrical about the beauty and power of this so-called ‘imaginary’ number to a sceptical Dr Rutherford. Dr Michael Brooks, author of The Maths That Made Us, tells the surprising story of the
